plutôt: identifiant numérique d’objet
« The objects identified by DOI names may be of any form -digital, physical, or abstract - as all these forms may be necessary parts of a content management system. The DOI system is an abstract framework which does not specify a particular context of its application, but is designed with the aim of working over the Internet. »
Norman Paskin, « Digital Object Identifier (DOI®) System »
DataCite
• Global consortium carried by local institutions• Focused on improving the scholarly infrastructure around
datasets and other non-textual information• Focused on working with data centres and organisations that
hold data• Providing standards, workflows and best-practice• Initially, but not exclusively based on the DOI system
• Memorandum of Understanding, Paris, February 2009• Officially founded December 1st 2009 in London

DataCite
The DataCite registration agency– Maintains the resolution infrastructure– Maintains a searchable database of metadata– Manages the identifiers over the long term– Establishes and shares best practice
Publishing agents (data centres, research institutes, data publishers) are responsible for– Quality assurance – Content storage and access – Creating the identifiers– Creating and updating metadata

DOIs in Use: DataCite
CrossRef has registered more than 51 million DOIs on behalf of scholarly publishers. But CrossRef DOIs are not the only DOIs available in the scholarly community. DOIs for datasets associated with scholarly research are being registered by institutions in the DataCite network. DataCite and CrossRef have committed to the interoperability of their DOIs. Ideally, scholarly content like journals will cite related data by the appropriate DataCite DOI, and in return, the data record will cite the relevant article’s CrossRef DOI. (from CrossRef Quarterly, January 2012)
Bridging the gap
Connecting article and underlying data via DOI:
The dataset:Storz, D et al. (2009): Planktic foraminiferal flux and faunal composition of sediment trap
L1_K276 in the northeastern Atlantic. http://dx.doi.org/10.1594/PANGAEA.724325
Is supplement to the article:Storz, David; Schulz, Hartmut; Waniek, Joanna J; Schulz-Bull,
Detlef; Kucera, Michal (2009): Seasonal and interannual variability of the planktic foraminiferal flux in the vicinity of the Azores Current.
Deep-Sea Research Part I-Oceanographic Research Papers, 56(1),107-124,

Data citation
Bridging the gap
• DataCite supports researchers by enabling them to locate, identify, and cite research datasets with confidence
• DataCite supports data centres by providing workflows and standards for data publication
• DataCite supports publishers by enabling linking from articles to the underlying data

DataCite Metadata 2.2 XML Schema
• Service for displaying DataCite metadata
• Different formats (BibTeX, RIS, RDF, etc.)
• Content Negotation (through MIME-Typ)
– Access through DOI proxy (http://dx.doi.org)
– First implemented by CNRI and CrossRef:
• Documentation:
• http://www.crosscite.org/cn/
• Service for displaying DataCite metadata in different formats (BibTeX, RIS, RDF, etc.)
• A particular representation of the metadata can be requested via content negotiation or by using DOI proxy (the "http://dx.doi.org" formulation as a URL) and MIME-type
• Documentation: http://www.crosscite.org/cn/

ORCID and DataCite Interoperability Network
« ODIN will build on the ORCID and DataCite initiatives to uniquely identify scientists and data sets and connect this information across multiple services and infrastructures for scholarly communication.
It will address some of the critical open questions in the area: Referencing a data object; Tracking of use and re-use; Links between a data object, subsets, articles, rights statements and every person involved in its life-cycle. »
